VALVE.

Specification of LettersPatent.

Patented July 6, 1915.

Application filed June 3, 1914.. Serial No. 842,551.

To all whom it may concern:

Be it known that I, JAMES H. RAYMAKER, a citizen of the United States, and resident of Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Valves; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to provide for instantaneous stopping of the fiow of a fluid in a circulating system by means of a novel, simple, economical and efficient mechanism including a quick-closing non-jarring and anti-friction valve that is normally held off seat and automatically or manually released to effect the desired result.

Figure 1 of the drawings represents an elevation of a valve-casing, and valve release and closing mechanism therewith; Fig. 2, a vertical sectional view indicated by line 2-2 in Fig. 3, said Fig. 3, being a horizontal sectional view indicated by line 3-3 in Fig. 1.

Referring by numerals to the drawings, 4 indicates a main section of a valve-casing and 5 the seat therein for the valve 6 having a shank 7 provided with an angular orifice having match fit on an angular end of the valve-stem 8, whereby a rigid connection is established between said valve and its stem. The valve-stem has bearing in a bushing 9 that is screw-threaded in a boss 10 of a pocket 11 of the valve-casing that is bolted to the main section 4 of the same to close an opening therein, and said valve-stem is provided with a conical shoulder 12 that fits a seat for the same in said bushing. When there is pressure on the inner end of the valve-stem, the shoulder of said stem is in fluid-tight engagement with its seat, whereby the use of any packing for the aforesaid stemis obviated.

In detachable rigid connection with the outer end of the valve-stem is a lever 13 and in sliding engagement with the lever is a weight 14. By means of a set-screw 15 therewith, the weight is heldin adjusted position on the lever. A lateral projection 16 of the lever is shown provided with an antifriction roller 17 that engages a hook-latch 18 when the valve is swung ofl seat into the pocket-section 11 of its casing, and the latch is pivotally suspended in connection with a shackle 19 depending from a frame 20 attached to the main section of said casing and supporting a solenoid 21. A slotted arm 18 of the latch engages a pin 22 extending laterally from the lower end of a core 23 slidable in the solenoid, and a predetermined energization of said solenoid results in an upward movement of said plunger to unlatch said lever, whereby there is instantaneous seating of the valve by gravity of the weight on the valve-stem lever. However it is within the scope of my invention, as herein claimed, to provide any suitable means by which to effect a retraction of the latch from working position, a11- tomatically or otherwise, and thus permit gravity seating of the valve. To insure proper seating of the valve, its casing is provided with suitably disposed inner guide lugs 24 adjacent to the seat 5.

To prevent the jar, that would otherwise result in the seating of the valve, the valvestem lever 13 is pivotally coupled to a link 25 of a toggle, the other link 26 of the toggle is likewise in connection with the pocket-section 11 of the valve-casing, and similarly connected to the joint of the toggle-links is a forked head 27 of a rod 28 guided in a bracket 29 also in pivotal connection with said pocket, the rod serving as a support for a sufficiently stiff spiral spring 30, the ends of which abut said bracket and a tensionnut 31 adjustable on said rod. To hold the tension nut in adjusted position, against expansive force of the spring 30, lock-nuts 32 are employed on the rod aforesaid. Hence when the valve-stem lever 18 is unlatched, the downward movement thereof results in a straightening of the toggle links 25, 26, against resistance of the spring 30, and the valve 6 finds its seat without shock, the proper tension of said spring being determined by an adjustment of the nuts 31, 32, on the rod 28.

From the foregoing it willbe understood that the pocket-section 1.1, valve 6, valvestem 8, valve-stem lever 13, toggle links 25, 26, rod 28 and spring may be removed together from the main section 4 of the valve-casing, in order to obtain ready access to said main section of said casing whenever desirable.

By employment of the anti-friction roller 17 in opposition to the hook-latch 18, the

slightest possible pull on said latch will result in a release of the valve-stem lever 13. However the gravity of the weight 14: on

the lever tends to make the anti-friction roller therewith bind tight in the latch when said lever is in horizontal position.

I claim:

1. The combination of a valve-casing provided with a pocket, the valve having a stem for which said pocket is provided with a bearing, a weighted lever fast on the outer end of the stem, means for latching the lever in position to hold the valve off seat in said pocket, a toggle having the links thereof pivotally connected to the aforesaid lever and pocket, a rod extending from the joint Copies of this patent may be obtained for pivotally connected to the aforesaid lever and pocket, a rod extending from the joint of the toggle a rod-guide in pivotal connection with the pocket, and a spring arranged to resist leverage on said toggle when said lever is released from the position aforesaid.

3. The combination of a valve-casing provided with a pocket, the valve having a stem for which said pocket is provided with a bearing, a weighted lever fast on the outer end of the stem, means for latching the lever in position to hold the valve olf seat in said pocket, a toggle having the links thereof pivotally connected to the aforesaid lever and pocket, and a spring arranged to resist leverage on said toggle when said lever is released from the position aforesaid.

In testimony that I claim the foregoing I have hereunto set my hand at Sheboygan Falls in the county of Shehoygan and State of Wisconsin in the presence of two witnesses.
